Solar cell
The electricity generated by the solar cell of the
watch is stored by a built-in battery. Leaving or
using the watch where it is not exposed to light
causes the battery to run down. Make sure the
watch is exposed to light as much as possible.
• When you are not wearing the watch on your
wrist, position the face so it is pointed at a
source of bright light.
• You should try to keep the watch outside of
your sleeve as much as possible. Charging is
reduced significantly if the face is covered only
partially.
E-1
• The watch continues to operate, even when it is not exposed to light.
Leaving the watch in the dark can cause the battery to run down, which will
cause some watch functions to be disabled. If the battery goes dead, you
will have to re-configure watch settings after recharging. To ensure normal
watch operation, be sure to keep it exposed to light as much as possible.

Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting
accordingly.
• This watch is designed to pick up the time calibration signals transmitted in
Germany (Mainflingen), England (Anthorn), the United States (Fort Collins),
China (Shangqiu), and Japan (Fukushima, Fukuoka/Saga).
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time
calibration signal. You also can perform a manual procedure to set the time
and date, when necessary.
• The first thing you should do after purchasing this watch is to specify
your Home City (the city where you normally will use the watch). For
more information, see “To specify your Home City” below.
• When using the watch outside the areas covered by the time signal
transmitters, you will have to adjust the current time setting manually as
required. See “Timekeeping” (page E-94) for more information about manual
time settings.
E-12
• The U.S. time calibration signal can be picked up by the watch while in
North America. The term “North America” in this manual refers to the area
that consists of Canada, the continental United States, and Mexico.

your Home City code. If it does not, it should adjust automatically after the
next auto receive operation (in the middle of the night). You also can
perform manual receive (page E-27) or you can set the time manually
(page E-96).
• The watch will receive the time calibration signal automatically from the
applicable transmitter (in the middle of the night) and update its settings
accordingly. For information about the relationship between city codes and
transmitters, see page E-18 and “Transmitters” (page E-110).
• See the maps under “Approximate Reception Ranges” (page E-19) for
information about the reception ranges of the watch.
• You can disable time signal reception, if you want. See “To turn auto receive
on and off” on page E-29 for more information.
E-14
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration
signal: auto receive and manual receive.
• Auto Receive
With auto receive, the watch receives the time calibration signal automatically
up to six times a day. When any auto receive is successful, the remaining
auto receive operations are not performed. For more information, see “About
Auto Receive” (page E-22).
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press
of a button. For more information, see “To perform manual receive” (page E-27).
E-15
Important!
• When getting ready to receive the time calibration signal, position the watch
as shown in the nearby illustration, with its 12 o’clock side facing towards a
window. This watch is designed to receive a time calibration signal late at
night. Because of this, you should place the watch near a window as shown
in the illustration when you take it off at night. Make sure there are no metal
objects nearby.

Note
• When a calibration time is reached, the watch will receive the calibration
signal only if it is in either the Timekeeping Mode or World Time Mode.
Reception is not performed if a calibration time is reached while you are
configuring settings.
• Auto receive of the calibration signal is designed to be performed early in
the morning, while you sleep (provided that the Timekeeping Mode time is
set correctly). Before going to bed for the night, remove the watch from your
wrist, and put it in a location where it can receive the signal easily.
E-23
• The watch receives the calibration signal for two to seven minutes everyday
when the time in the Timekeeping Mode reaches a calibration time. Do not
perform any button operation within seven minutes before or after the
calibration times. Doing so can interfere with correct calibration.
• Remember that reception of the calibration signal depends on the current
time in the Timekeeping Mode. The receive operation will be performed
whenever the display shows any one of the calibration times, regardless of
whether or not the displayed time actually is the correct time.
E-24
About the Signal Indicator
The signal indicator shows the strength of the calibration signal being
received. For best reception, be sure to keep the watch in a location where
signal strength is strongest. The signal indicator is displayed while an auto or
manual receive operation is in progress.

Strong
(Level 3)
• Even in an area where signal strength is strong, it takes about 10 seconds
for signal reception to stabilize enough for the signal indicator to indicate
signal strength.
E-25
• Use the signal indicator as a guide for checking signal strength and for
finding the best location for the watch during signal receive operations.
• Following reception of the time calibration signal and calibration of the
watch’s time setting, the Level 3 signal indicator will remain on the display
in all modes. The Level 3 signal indicator will not be displayed if signal
reception was unsuccessful or after you adjust the current time setting
manually.
• The Level 3 signal indicator is displayed only when the watch is able to
receive both time and date data successfully. It does not appear when only
time data is received.
• The Level 3 signal indicator indicates that at least one of the auto
calibration signal receive operations was successful. Note, however, that
the Level 3 signal indicator disappears from the display each day when the
first auto receive operation of the day is performed.

E-33
Altimeter
The watch’s altimeter uses a pressure sensor to detect current air pressure,
which is then used to estimate the current altitude based on ISA (International
Standard Atmosphere) preset values. You can specify a reference altitude,
which the watch will use to calculate your current altitude based on the value
you specify. Altimeter functions also include storage of measurement readings
in memory.
Important!
• This watch estimates altitude based on air pressure. This means that
altitude readings for the same location may vary if air pressure changes.
• The semiconductor pressure sensor used by the watch for altitude readings
also is affected by temperature. When taking altitude readings, make sure
the watch is not subjected to temperature changes.
• To avoid the effect of sudden temperature changes during readings, keep
the watch on your wrist in direct contact with your skin.
E-34
• Do not rely upon this watch for altitude readings or perform button
operations while sky diving, hang gliding, or paragliding, while riding a
gyrocopter, glider, or any other aircraft, or while engaging in any other
activity where there is the chance of sudden altitude changes.
• Do not use this watch for taking altitude readings in applications that
demand professional or industrial level precision.
• Remember that the air inside of a commercial aircraft is pressurized.
Because of this, the readings produced by this watch will not match the
altitude readings announced or indicated the flight crew.
How the Altimeter Measures Altitude
The altimeter can measure altitude based on its own preset values, or a
reference altitude specified by you.
When you measure altitude based on preset values
Data produced by the watch’s barometric pressure sensor is converted to
approximate altitude based on ISA (International Standard Atmosphere)
conversion values stored in watch memory.
E-35
When you measure altitude using a reference altitude specified by you
After you specify a reference altitude, the watch will use that value to convert
the current barometric pressure reading to altitude.
• When mountain climbing, you can specify a
reference value in accordance with a marker
B
along the way or altitude information from a
map. After that, altitude readings produced
A
400
by the watch will be more accurate than they
would without a reference altitude.
Displaying Your Current Altitude
You can use the procedure described in this section to display your current
altitude. If you leave the watch in the Altimeter Mode, it will update the
displayed altitude value regularly, and indicate reading-to-reading changes in
a window in the upper left of the display (page E-38).
You can select either of the following two altitude measurement intervals.
0'05": Readings at five-second intervals for one hour
2'00": Readings at five-second intervals for the first three minutes followed
by two-minute intervals for 10 hours
E-36
• For information about configuring settings for the altitude reading interval
and duration, see “To specify the altitude reading interval” on page E-42.
Important!
• The procedure below simply displays a value indicating your current
altitude, without recording it in watch memory. For information about
recording altitude readings in watch memory, see “Saving Altitude Readings
in Memory” (page E-43).

• The watch will start altitude measurement
and display the result.
• It can take up to four or five seconds for the
first altitude reading to appear.
2. If you leave the watch in the Altimeter Mode,
the current altitude value and the altitude
change value will be updated according to the
altitude reading interval (page E-42).
• If you want to restart the operation at any
point, press C.
3. To stop taking altitude readings, press D to
exit the Altimeter Mode.
Notes
• Normally, displayed altitude values are based on the watch’s preset
conversion values. You also can specify a reference altitude, if you want.
See “Specifying a Reference Altitude” (page E-49).
• Altitude is displayed in units of 5 meters.
• The measurement range for altitude is –700 to 10,000 meters.
• An altitude reading may be displayed be a negative value in cases where
there is a reference altitude value specified or because of certain
atmospheric conditions.
• The displayed altitude value changes to xxxx meters if an altitude reading
falls outside the measurement range. The altitude value will be displayed
again as soon as the altitude reading is within the allowable range.
• During altitude measurements, the watch may not be able to update its
timekeeping display contents normally. Correct timekeeping is maintained
internally, however.

Saving Altitude Readings in Memory
The following describes the different types of records the watch creates for
altitude readings.
• You can take manual altitude readings, which are stored in memory along
with the date (year, month, day) of the reading. There is enough memory to
hold up to 20 altitude records (readings).
• The Altimeter Mode has a stopwatch (which is independent of the watch’s
Stopwatch Mode) that you can use to time your climbs. While the Altimeter
Mode stopwatch is running, the watch takes altitude readings automatically
(without storing them in memory). Each time you reset the Altimeter Mode
stopwatch to all zeros, the highest altitude, lowest altitude, cumulative
ascent, and cumulative descent achieved during the last Altimeter Mode
stopwatch session are stored in a “current stopwatch session record”.
• A separate “historical record” keeps track of the highest altitude, lowest
altitude, cumulative ascent, and cumulative descent of all past Altimeter
Mode stopwatch sessions.
E-43
To take a manual altitude reading
1. Press C to enter the Altimeter Mode (page E-11).
2. Hold down C for about one second until the watch beeps and REC
flashes on the display.
• This indicates that the current altitude reading, current date (year,
month, day), and time are being saved to memory.
3. REC will stop flashing and the watch will return to the Altimeter Mode
automatically after data save is complete.
• Memory can hold up to 20 altitude records. Storing a new reading while

Other Altimeter Mode Features
This section explains other features and settings that are available in the
Altimeter Mode. Note that all of the information in this section applies to all
types of Altimeter Mode measurements, unless specifically indicated
otherwise.
Specifying a Reference Altitude
After you specify a reference altitude, the watch adjusts its air-pressure-toaltitude conversion calculation accordingly. The altitude readings produced by
this watch are subject to error caused by changes in air pressure. Because of
this, we recommend that you update the reference altitude whenever one is
available during your climb.

temperature falls outside the range of –10.0°C to 60.0°C. The temperature
value will reappear as soon as the measured temperature is within the
allowable range.
• In some areas, barometric pressure is expressed in millibars (mb) instead
of hectopascals (hPa). It really makes no difference, because 1hPa = 1mb.
• See “Barometer and Thermometer Precautions” (page E-115) for important
precautions.
E-60
Barometric Pressure Graph
Barometric pressure indicates changes in the atmosphere. By monitoring
these changes you can predict the weather with reasonable accuracy.
This watch takes barometric pressure readings automatically every two hours
(at the top of each even-numbered hour), regardless of its current mode.
Measurement results are used to produce barometric pressure graph and
barometric pressure change indicator readings.
The barometric pressure graph shows the results of previous measurements
for up to 24 hours. The horizontal axis of the graph represents time, with each
dot standing for two hours. The rightmost dot represents the most recent
reading. The vertical axis of the graph represents barometric pressure, with
each dot standing for the relative difference between its reading and that of
the dots next to it. Each dot represents 1hPa.
The following shows how to interpret the data that appears on the barometric
pressure graph.
E-61
A rising graph generally means improving weather.
A falling graph generally means deteriorating weather.
Note that if there are sudden changes in weather or
temperature, the graph line of past measurements may run

Questions & Answers
Question: How does the barometer work?
Answer: Barometric pressure indicates changes in the atmosphere, and by
monitoring these changes you can predict the weather with
reasonable accuracy. Rising atmospheric pressure indicates good
weather, while falling pressure indicates deteriorating weather
conditions.
The barometric pressures that you see in the newspaper and on the
TV weather report are measurements corrected to values measured
at 0 m sea level.
E-81
Question: How does the altimeter work?
Answer: Generally, air pressure and temperature decrease as altitude
increases. This watch bases its altitude measurements on
International Standard Atmosphere (ISA) values stipulated by the
International Civil Aviation Organization (ICAO). These values define
relationships between altitude, air pressure, and temperature.

E-83
There are two standard methods of expressing altitude: Absolute altitude and
relative altitude. Absolute altitude expresses an absolute height above sea
level. Relative altitude expresses the difference between the height of two
different places.

E-84
Precautions Concerning Simultaneous Measurement of Altitude and
Temperature
Though you can perform altitude and temperature measurements at the same
time, you should remember that each of these measurements requires
different conditions for best results. With temperature measurement, it is best
to remove the watch from your wrist in order to eliminate the effects of body
heat. In the case of altitude measurement, on the other hand, it is better to
leave the watch on your wrist, because doing so keeps the watch at a
constant temperature, which contributes to more accurate altitude
measurements.
• To give altitude measurement priority, leave the watch on your wrist or in
any other location where the temperature of the watch is kept constant.
• To give temperature measurement priority, remove the watch from your
wrist and allow it to hang freely from your bag or in another location where
it is not exposed to direct sunlight. Note that removing the watch from your
wrist can affect pressure sensor readings momentarily (page E-115).
E-85
Power Supply
This watch is equipped with a solar cell and a special rechargeable battery
(secondary battery) that is charged by the electrical power produced by the
solar cell. The illustration shown below shows how you should position the
watch for charging.
Example: Orient the watch so its face is
pointing at a light source.
• The illustration shows how to position a
watch with a resin band.
• Note that charging efficiency drops when
any part of the solar cell is blocked by
clothing, etc.
• You should try to keep the watch outside
of your sleeve as much as possible.
Charging is reduced significantly if the
face is covered only partially.
E-86
Solar cell
Important!
• Storing the watch for long periods in an area where there is no light or
wearing it in such a way that it is blocked from exposure to light can cause
rechargeable battery power to run down. Be sure that the watch is exposed
to bright light whenever possible.
• This watch uses a special rechargeable battery to store power produced by
the solar cell, so regular battery replacement is not required. However, after
very long use, the rechargeable battery may lose its ability to achieve a full
charge. If you experience problems getting the special rechargeable battery
to charge fully, contact your dealer or CASIO distributor about having it
replaced.
• Never try to remove or replace the watch’s special battery yourself. Use of
the wrong type of battery can damage the watch.
• All data stored in memory is deleted, and the current time and all other
settings return to their initial factory defaults whenever battery power drops
to Level 5 (page E-88) and when you have the battery replaced.
• Turn on the watch’s Power Saving function (page E-107) and keep it in an
area normally exposed to bright light when storing it for long periods. This
helps to keep the rechargeable battery from going dead.

• Even if battery power is at Level 1 or Level 2, the Barometer/Thermometer
Mode or Altimeter Mode sensor may be disabled if there is not enough
voltage available to power it sufficiently. This is indicated by LMH on the
display.
• If LMH appears frequently, it probably means that remaining battery power
is low. Leave the watch in bright light to allow it to charge.

Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid
leaving the watch in the areas described below whenever charging its
rechargeable battery.
Also note that allowing the watch to become very hot can cause its liquid
crystal display to black out. The appearance of the LCD should become
normal again when the watch returns to a lower temperature.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can
cause it to become quite hot. Take care when handling the watch to
avoid burn injury. The watch can become particularly hot when exposed
to the following conditions for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight

Read This Before You Set the Time and Date!
This watch is preset with a number of city codes, each of which represents
the time zone where that city is located. When setting the time, it is important
that you first select the correct city code for your Home City (the city where
you normally use the watch). If your location is not included in the preset city
codes, select the preset city code that is in the same time zone as your
location.
• Note that all of the times for the World Time Mode city codes (page E-67)
are displayed in accordance with the time and date settings you configure in
the Timekeeping Mode.
To set the time and date manually
1. In the Timekeeping Mode, hold down A until the city code starts to flash.
This indicates the setting screen.
2. Use E and B to select the city code you want.
• Make sure you select your Home City code before changing any other

E-98
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour
from Standard Time. Remember that not all countries or even local areas use
Daylight Saving Time.
The time calibration signals transmitted from Mainflingen (Germany), Anthorn
(England), or Fort Collins (the United States) include both Standard Time and
DST data. When the Auto DST setting is turned on, the watch switches
between Standard Time and DST (summer time) automatically in accordance
with the signals.
• Though the time calibration signal transmitted by the Fukushima and
Fukuoka/Saga, Japan transmitters include summer time data, summer time
currently is not implemented in Japan (as of 2008).
• The default DST setting is Auto DST (AvtA) whenever you select LON,
PAR, BER, ATH, HKG, TPE, TYO, LAX, DEN, CHI, or NYC
as your Home City code.
• If you experience problems receiving the time calibration signal in your
area, it probably is best to switch between Standard Time and Daylight
Saving Time (summer time) manually.

Reference
This section contains more detailed and technical information about watch
operation. It also contains important precautions and notes about the various
features and functions of this watch.
Auto Return Features
• The watch returns to the Timekeeping Mode automatically if you do not
perform any button operation for two or three minutes in the Data Recall,
Alarm, Receive, or Barometer/Thermometer Mode.
• If you do not perform any button operation for 21 or 22 hours while in the
Altimeter Mode, the watch will return to the Timekeeping Mode
automatically.
• If you leave a screen with flashing digits on the display for two or three
minutes without performing any operation, the watch exits the setting
screen automatically.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing
when you last exited the mode appears first.
E-101
Scrolling
The E and B buttons are used on the setting screen to scroll through data
on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Sensor Malfunction Indicator
Subjecting the watch to strong impact can cause sensor malfunction or
improper contact of internal circuitry. When this happens, ERR (error) will
appear on the display and sensor operations will be disabled.
Barometric Pressure
Measurement
E-102
Altitude
Measurement
• If ERR appears while a measurement operation is being performed in a
sensor mode, restart the measurement. If ERR appears on the display
again, it can mean there is something wrong with the sensor.
• Even if battery power is at Level 1 or Level 2, the Barometer/Thermometer
Mode or Altimeter Mode sensor may be disabled if there is not enough
voltage available to power it sufficiently. In this case, ERR will appear on
the display. This does not indicate malfunction, and sensor operation should
resume once battery voltage returns to its normal level.
• If ERR keeps appearing during measurement, it could mean there is a
problem with the applicable sensor.
Whenever you have a sensor malfunction, be sure to take the watch to
your original dealer or nearest authorized CASIO distributor as soon as
possible.
E-103
Button Operation Tone
The button operation tone sounds any time you
press one of the watch’s buttons. You can turn the
button operation tone on or off as desired.
• Even if you turn off the button operation tone,
the alarm, Hourly Time Signal, and Countdown
Timer Mode alarm all operate normally.
To turn the button operation tone on and off
Mute indicator
In any mode (except when a setting screen is on
the display), hold down D to toggle the button
operation tone on (MUTE not displayed) and off
(MUTE displayed).
• Since the D button also is the mode change button, holding it down to turn
the button operation on or off also causes the watch’s current mode to
change.
• The MUTE indicator is displayed in all modes when the button operation
tone is turned off.
E-104
Power Saving
When turned on, Power Saving enters a sleep
state automatically whenever the watch is left for
a certain period in an area where it is dark. The
table below shows how watch functions are
affected by Power Saving.

• Wearing the watch inside the sleeve of clothing can cause it to enter the
sleep state.
• The watch will not enter the sleep state while the digital time is between
6:00 AM and 9:59 PM. If the watch is already in the sleep state when the
digital time reaches 6:00 AM, however, it will remain in the sleep state.
• The watch will not enter the sleep state while it is in the Barometer/
Thermometer, Altimeter, Receive, Countdown Timer, or Stopwatch Mode.
When the watch is left in any mode besides the Countdown Timer and
Stopwatch Mode, it will return to the Timekeeping Mode automatically after
a specific amount of time (page E-101). Then if left in the dark for the
elapsed time indicated in the table above, the watch will enter a sleep state.
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area. It can take up to two seconds for the
display to turn on.
• Press any button.

E-107
Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time being set.
• The time calibration signal bounces off the ionosphere. Because of this,
such factors as changes in the reflectivity of the ionosphere, as well as
movement of the ionosphere to higher altitudes due to seasonal
atmospheric changes or the time of day may change the reception range of
the signal and make reception temporarily impossible.
• Even if the time calibration signal is received properly, certain conditions
can cause the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes
priority over any time settings you make manually.
• The watch is designed to update the date and day of the week
automatically for the period January 1, 2001 to December 31, 2099. Setting
of the date by the time calibration signal cannot be performed starting from
January 1, 2100.
• This watch can receive signals that differentiate between leap years and
non-leap years.
E-108
• Though this watch is designed to receive both time data (hour, minutes,
seconds) and date data (year, month, day), certain signal conditions can
limit reception to time data only.
• If you are in an area where proper time calibration signal reception is
impossible, the watch keeps the time with the precision noted in
“Specifications”.
• If you have problems with proper time calibration signal reception or if the
time setting is wrong after signal reception, check your current city code,
DST (summer time) (page E-96), and auto receive settings (page E-29).
• The Home City setting reverts to the initial default of TYO (Tokyo)
whenever the battery power level drops to Level 5 or when you have the
rechargeable battery replaced. If this happens, change the Home City to the
setting you want (page E-13).
E-109
Transmitters
The time calibration signal received by this watch depends on the currently
selected Home City code (page E-13).
• When a U.S. time zone is selected, the watch receives the time calibration
signal transmitted from the United States (Fort Collins).
• When a Japanese time zone is selected, the watch receives the time
calibration signal transmitted from Japan (Fukushima and Fukuoka/Saga).
• When a European time zone is selected, the watch receives the time
calibration signals transmitted from Germany (Mainflingen) and England
(Anthorn).
• When a China time zone is selected, the watch receives the time calibration
signals transmitted from China (Shangqiu City).
• When your Home City is LON, PAR, BER, or ATH (which can receive both
the Anthorn and Mainflingen signals), the watch first tries to pick up the
signal it last successfully received. If that fails, it tries the other signal. For
the first receive after you select your Home City, the watch tries the nearest
signal first (Anthorn for LON, Mainflingen for PAR, BER, and ATH).
E-110
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to
59 causes the minutes to be increased by 1. In the range of 00 to 29, the
seconds are reset to 00 without changing the minutes.
• With the 12-hour format, the P (PM) indicator appears on the display for
times in the range of noon to 11:59 p.m. and no indicator appears for times
in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59,
without any indicator.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping
Mode is applied in all modes.
• The watch’s built-in full automatic calendar makes allowances for different
month lengths and leap years. Once you set the date, there should be no
reason to change it except when battery power drops to Level 5 (page
E-88).
• The current time for all city codes in the Timekeeping Mode and World Time
Mode is calculated in accordance with the Coordinated Universal Time
(UTC) for each city, based on your Home City time setting.
E-111
• The UTC offset is a value that indicates the time difference between a
reference point in Greenwich, England and the time zone where a city is
located.
• The letters “UTC” is the abbreviation for “Coordinated Universal Time”,
which is the world-wide scientific standard of timekeeping. It is based upon
carefully maintained atomic (cesium) clocks that keep time accurately to
within microseconds. Leap seconds are added or subtracted as necessary
to keep UTC in sync with the Earth’s rotation.
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after
very long use.
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• The watch may emit an audible sound whenever the display is illuminated.
This is due to vibration of the EL panel used for illumination, and does not
indicate malfunction.
• Frequent use of illumination runs down the battery.
E-112
Auto light switch precautions
• The auto light switch is turned off automatically whenever battery power is
at Level 4 (page E-88).
• Wearing the watch on the inside of your wrist, movement of your arm, or
vibration of your arm can cause frequent activation of the auto light switch
and illumination of the display. To avoid running down the battery, turn off
the auto light switch whenever engaging in activities that might cause
frequent illumination of the display.
• Note that wearing the watch under your sleeve while the auto light switch is
turned on can cause frequent illumination of the display and can run down
the battery.
More than 15 degrees
too high
• Illumination may not turn on if the face of the
watch is more than 15 degrees above or below
parallel. Make sure that the back of your hand
is parallel to the ground.
• Illumination turns off in about one second, even
if you keep the watch pointed towards your
face.
E-113
• Static electricity or magnetic force can interfere with proper operation of the
auto light switch. If illumination does not turn on, try moving the watch back
to the starting position (parallel with the ground) and then tilt it back towards
your face again. If this does not work, drop your arm all the way down so it
hangs at your side, and then bring it back up again.
• Under certain conditions, illumination does not turn on until about one
second after you turn the face of the watch towards you. This does not
necessarily indicate malfunction.
• You may notice a very faint clicking sound coming from the watch when it is
shaken back and forth. This sound is caused by mechanical operation of
the auto light switch, and does not indicate a problem with the watch.
E-114
Barometer and Thermometer Precautions
• The pressure sensor built into this watch measures changes in air
pressure, which you can then apply to your own weather predictions. It is
not intended for use as a precision instrument in official weather prediction
or reporting applications.
• Sudden temperature changes can affect pressure sensor readings.
• Temperature measurements are affected by your body temperature (while
you are wearing the watch), direct sunlight, and moisture. To achieve a
more accurate temperature measurement, remove the watch from your
wrist, place it in a well ventilated location out of direct sunlight, and wipe all
moisture from the case. It takes approximately 20 to 30 minutes for the
case of the watch to reach the actual surrounding temperature.
E-115
Pressure Sensor and Temperature Sensor Calibration
The pressure sensor and temperature sensor built into the watch are
calibrated at the factory and normally require no further adjustment. If you
notice serious errors in the pressure readings and temperature readings
produced by the watch, you can calibrate the sensor to correct the errors.
Important!
• Incorrectly calibrating the barometric pressure sensor can result in incorrect
readings. Before performing the calibration procedure, compare the
readings produced by the watch with those of another reliable and accurate
barometer.
• Incorrectly calibrating the temperature sensor can result in incorrect
readings. Carefully read the following before doing anything.
Compare the readings produced by the watch with those of another
reliable and accurate thermometer.
If adjustment is required, remove the watch from your wrist and wait for 20
or 30 minutes to give the temperature of the watch time to stabilize before
adjusting.

• Do not use this watch for scuba diving or other types of diving that requires
air tanks.
E-124
• Watches that do not have WATER RESIST or WATER RESISTANT marked
on the back cover are not protected against the effects of sweat. Avoid
using such a watch under conditions where it will be exposed to large
amounts of sweat or moisture, or to direct splashing with water.
• Even if a watch is water-resistant, do not operate its buttons or crown while
it is submersed in water or wet.
• Even if a watch is water-resistant, avoid wearing it in the bath or in areas
where detergents (soap, shampoo, etc.) are being used. Such conditions
can reduce water resistance.
• After submersion in seawater, use plain water to rinse all salt and dirt from
the watch.
• In order to maintain water resistance, have the gaskets of your watch
replace periodically (about once every two or three years).
• A trained technician will know how to check your watch for proper water
resistance whenever you have its battery replaced. Battery replacement
requires the use of special tools. Always request battery replacement from
your original retailer or from an authorized CASIO Service Center.
• Some water-resistant watches come with fashionable leather bands. Avoid
swimming, washing, or any other activity that causes direct exposure of a
leather band to water.
E-125
• The inside surface of the watch glass may fog when the watch is exposed
to a sudden drop in temperature. No problem is indicated if the fogging
clears up relatively quickly. If the fogging does not clear or if water has
gotten into the watch, take the watch in for repair immediately.
• Continued use of the watch with water inside can result in damage to
electronic and mechanical components, the face of the watch, etc.
Band
• Tightening the band too tightly can cause you to sweat and make it hard for
air to pass under the band, which can lead to skin irritation. Do not fasten
the band too tightly. There should be enough room between the band and
your wrist so you can insert your finger.
• Deterioration, rust, or corrosion of the band can cause it to break, which
may result in the watch falling off your wrist and becoming lost. Be sure to
take good care of the band and keep it clean. Should you notice any
breakage, discoloration, looseness or other problem with the band,
immediately contact your original retailer or an authorized CASIO Service
Center to have it checked, repaired, or replaced. Note that you will be
charged for any repair or replacement of the band.
E-126
Temperature
• Never leave the watch on the dashboard of a car, near a heater, or in any
other location that is subject to very high temperatures. Do not leave the
watch where it will be exposed to very low temperatures, either.
Temperature extremes can cause the watch to lose or gain time, to stop, or
otherwise malfunction.
• Leaving the watch in an area hotter than +60°C (140°F) for long periods
can lead to problems with its LCD. The LCD may become difficult to read at
temperatures lower than 0°C (32°F) and greater than +40°C (104°F).
Impact
• Your watch is designed to withstand impact incurred during normal daily
use and light activity such as playing catch, tennis, etc. Dropping the watch
or otherwise subjecting it to strong impact, however, can lead to
malfunction.
Note that watches with shock-resistant designs (G-SHOCK, Baby-G, G-ms)
can be worn while operating a chain saw or engaging in other activities that
generate strong vibration, or while engage in strenuous sports activities
(motocross, etc.).
E-127
Magnetism
• Though your watch normally is not affected by magnetism, very strong
magnetism (from medical equipment, etc.) should be avoided because it
can cause malfunction and damage to electronic components.
• Though operation of your watch normally is not affected by magnetism, its
accuracy may be affected if the watch itself becomes magnetized. Also,
very strong magnetism (from medical equipment, etc.) should be avoided
because it can cause malfunction of the watch and damage to electronic
components.
Electrostatic Charge
• Exposure to very strong electrostatic charge can cause the watch to display
the wrong time. Very strong electrostatic charge even can damage
electronic components.
• Electrostatic charge can cause the display to go blank momentarily or
cause a rainbow effect on the display.
E-128
Chemicals
• Do not allow the watch to come into contact with thinner, gasoline, solvents,
oils, or fats, or with any cleaners, adhesives, paints, medicines, or
cosmetics that contain such ingredients. Doing so can cause discoloration
of or damage to the case, resin band, leather band, and other parts.
Storage
• If you do not plan to use the watch for a long time, wipe it thoroughly free of
all dirt, sweat, and moisture, and store it in a cool, dry place.
Resin Components
• Allowing the watch to remain in contact with other items or storing it
together with other items for long periods while it is wet can cause the color
of the other items to transfer to the resin components of the watch. Be sure
to dry off the watch thoroughly before storing it and make sure it is not in
contact with other items.
• Leaving the watch where it is exposed to direct sunlight (ultraviolet rays) for
long periods or failure to clean dirt from the watch for long periods can
cause it to become discolored.
E-129
• Friction caused by certain conditions (frequent external force, sustained
rubbing, impact, etc.) can cause discoloration of painted components.
• If there are printed figures on the band, strong rubbing of the printed area
can cause discoloration.
• Failure to clean dirt from the watch for long periods can cause fluorescent
color to fade. Wash dirt off with water as soon as possible and then dry the
watch.
• Semi-transparent resin parts can become discolored due to sweat and dirt,
and if exposed to high temperatures for long periods.
• Contact an authorized CASIO Service Center to have resin components
replaced. Note that you will be charged for replacement costs.
Natural Leather and Imitation Leather Bands
• Allowing the watch to remain in contact with other items or storing it
together with other items while it is wet for long periods can cause the color
of the other items to transfer to the natural leather or imitation leather band
of the watch. Be sure to dry off the watch thoroughly before storing it and
make sure it is not in contact with other items.
E-130
• Leaving a leather band where it is exposed to direct sunlight (ultraviolet
rays) for long periods or failure to clean dirt from a leather band for long
periods can cause it to become discolored.
Important!
• Subjecting a natural leather or imitation leather band to rubbing or dirt can
cause color transfer and discoloration.
Metal Components
• Failure to clean dirt from a metal band can lead to formation of rust, even if
the band is stainless steel or plated. If the watch is exposed to sweat or
water, wipe it thoroughly with a soft, absorbent cloth and then store it in a
well-ventilated location to dry.
• To clean the band, use a soft toothbrush or similar tool to scrub it with a
weak solution of water and a mild neutral detergent. Take care to avoid
getting solution on the watch case.
E-131
Bacteria and Odor Resistant Band
• The bacteria and odor resistant band protects against odor generated by
the formation of bacteria from sweat, which ensures good comfort and
hygiene. In order to ensure maximum bacteria and odor resistance, keep
the band clean. Use an absorbent soft cloth to wipe the band clean of dirt,
sweat, and moisture. The bacteria and odor resistant band suppresses the
formation of organisms and bacteria. It does not protect against rash due to
allergic reaction, etc.
Display
• Display figures may be difficult to read when viewed from an angle.
Data Protection
• Allowing the battery to go dead, replacing the battery, or having the watch
repaired can cause all data in the watch’s memory to be lost. Note that
CASIO COMPUTER CO., LTD. assumes no responsibility for any damages
or losses caused by data lost due to malfunction or repair of the watch,
replacement of the battery, etc. Be sure to keep separate written copies of
all important data.
E-132
Sensors
• The sensors of this watch are precision instruments. Never try to take them
apart. Never try to insert any objects into the openings of sensors, and take
care to ensure that dirt, dust, or other foreign matter does not get into
sensors. After using the watch where it is immersed in saltwater, rinse it
thoroughly with fresh water.
E-133
User Maintenance
Caring for Your Watch
• A dirty or rusty case or band can soil the sleeve of your clothing, cause skin
irritation, and even interfere with watch performance. Be sure to keep the
case and band clean at all times. Rust tends to form easily after the watch
is exposed to seawater and then left without cleaning.
• Sometimes a smudge like pattern may appear on the surface of a resin
band. This will not have any affect on your skin or clothing. Wipe the band
with a cloth to clean it.
• Keep a leather band clean by wiping it with a dry cloth. Both resin bands
and leather band can become worn and cracked over time when subjected
to normal daily use.
• Should your band become badly cracked or worn, be sure to have it
replaced with a new one. Request band replacement from your original
retailer or an authorized CASIO Service Center. Note that you will be
charged for band replacement costs, even if your watch is still covered by
its warranty.
E-134
• Remember that you wear your watch next to your skin, just like a piece of
clothing. Because of this, you should always keep your watch clean. Use a
soft, absorbent cloth to wipe off any dirt, sweat, water, or other foreign
matter from the case and band.
Dangers of Poor Watch Care
Rust
• Though the stainless steel used for the watch is highly rust-resistant, rust
can form if the watch is not cleaned after it becomes dirty. Failure of oxygen
to come into contact with the metal because it is dirty causes breakdown of
the oxidization layer on the metal surface, which leads to the formation of
rust.
• Even if the surface of the metal appears clean, sweat and rust in crevasses
can soil the sleeves of clothing, cause skin irritation, and even interfere with
watch performance.
Premature Wear
• Leaving sweat or water on a resin band or storing it an area subject to high
moisture can lead to premature wear, cuts, and breaks.
E-135
Skin Irritation
• Individuals with sensitive skin or in poor physical condition may experience
skin irritation when wearing a watch. Such individuals should keep their
leather band or resin band particularly clean, or switch to a metal band.
Should you ever experience a rash or other skin irritation, immediately
remove the watch and contact a skin care professional.
Battery
• The special rechargeable (secondary) battery used by your watch is not
intended to be removed or replaced by you. Use of a rechargeable battery
other than the special one specified for this watch can damage the watch.
• The rechargeable battery is charged when the solar cell is exposed to light,
and so regular periodic replacement is not required. However, charging and
discharging of the battery over the years leads naturally to a loss in its
ability to sustain a charge and shortens its operating time. If this happens,
contact your original retailer or authorized CASIO Service Center.
